A transistor with gate, drain, and source terminals is known as a field-effect transistor (FET). FETs control the flow of current through a semiconductor by applying a voltage to the gate, which alters the conductivity between the drain and source. Wikipedia autodesk.com
in our case, we have an irf520 transistor and the pinout is like 
1: Gate 2: Drain 3: Source
PC Fan Pinout
Black: Ground Yellow: +5V, +12V or +24V (depends on fan model, usually 12V for desktops, 5V for laptops) Green: Sense. Used to measure RPM Blue: PWM control signal at 5V, 25kHz
